Thrash with thrushes

Yesterday
and today few hundreds of thrushes were migrating and feeding on the field in
front of the Ribachinskaya trap. We caught 52 of them for these two days: 26 Red-throated (Turdus ruficollis), 19 Naumann’s
(Turdus naumanni), 5 Dusky (Turdus eunomus) and by one Black-throated(Turdus atrogularis) and Song Thrush (Turdus philomelos) .

And
of cause, as every year, problems occurred with distinguishing sex, age and
even sometimes species (in Dusky – Naumann’s and Red-throated – Black-throated).
So we have a question to our colleagues from Finland who spent many time last
year at our station looking at thrushes: Jari, what did you finally find out???

Together with thrushes Sparrowhawks(Accipiter nisus) migrating because
it is so nice for them to have food storage flying by itself. Two females were
ringed today.
